All Implemented Interfaces:

GroupActionStrategy

public class ExternalIdCheckingGroupActionStrategy
extends AbstractGroupActionStrategy

A group action strategy that compares the remote group with a local group matched by external id. This adds support for renaming groups. As this class is unaware of other groups in the cache/from the remote, care must be taken to ensure no duplicates exist beforehand. This implementation also skips some checks from DefaultGroupActionStrategy, mostly related to groups of type GroupType.LEGACY_ROLE, so it is not intended as a drop in replacement for existing LDAP directories, even if they support the notion of external ids for groups.

Parameters:

internalGroup - the group matched by name from the internal directory or null if the group isn't present yet

groupMatchedByExternalId - the group matched by external id from the internal directory or null if there were no matches, only applicable for directories supporting special handling for groups with external ids

remoteGroup - the group from the remote directory

syncStartDate - the date at which the synchronisation was started, used to check for local modifications after sync start

directoryId - the id of the remote directory

Returns:

an object containing collections related to different types of handling new groups, one of which may contain the remote group if it should be handled

Throws:

OperationFailedException - if the group can't be correctly handled
